I drive a Duster 110BHP! Had done a check between XUV and Duster and my take is.... 1.I had a similar concern on Safety and XUV 500 lost on its Fiberglass Thighs (front wheel archs)! I think in a endeavour to reduce body weight safety is compromised here. 2. XUV wins for Space as it has better leg room in First as well as the second row! On the contrary Duster has a huge boot space, so this is entirely your take. 3. Duster is way way ahead in driving comfort and is a far better vehicle to handle compared to XUV. Also,with XUV I was not at all confident on sharp turns and curves compared to Duster. 4. Maintenance cost is yet unanswered but noteworthy is that for my First service I didnt pay a penny for duster and what more the vehicle was picked up and dropped after service to my door step that too without any cost!!!
